Description  
TheNexFlashNX26F011AandNX26F041ASerialFlash  
Memories are tailored for portable/mobile media-storage  
applicationsthattransferandstoredata,audioandimages.  
Manufactured using NexFlashs patented single transistor  
EEPROM memory cell, the NX26F011A and NX26F041A  
provide a high-density, low-voltage, low-power, and cost  
effective solution for battery-operated nonvolatile data  
storage requirements. The NX26F011A and NX26F041A  
can operate with a single 5V or 3V supply for Read, Write,  
and Erase. Power consumption is very low due to µA  
standbycurrentandfastErase/Writeperformance(asfast  
as5mspersector)thatminimizespower-ontime,resulting  
inahighlyefficientenergy-per-transferratio.TheNX26F011A  
andNX26F041Aoffer1M-bitsand4M-bitsofFlashmemory  
organized in sectors of 264 bytes each. Each sector is  
individually addressable through basic commands or  
control functions such as Reset, Read, Erase/Write, and  
Ready/Busy. The NXS (NexFlash Serial) 2-wire serial  
interface is ideal for use with microcontrollers since it only  
requirestwopins.Thisleavespinsnormallyusedforparallel  
Flash free for other uses. The NXS interface supports clock  
ratesasfastas16MHzandallowsformulti-devicecascading  
of up to 16 devices. It also simplifies PC-board layout and 11

opment is supported with the NexFlash Serial Flash  
Development Kit.
